Re: pterosaur take-off analog



Well said. By way of comparison, while sitting in a Piper J3 at idle power, on several occasions I've had a gust lift the plane entirely off the ground (only takes a 33 knot gust to do so in that plane). However, the plane immediately starts accelerating aftward and the relative windspeed drops too low to support the plane after approximately one second. The same happens with large pterosaurs. Your choices when that happens are to fly momentarily and then land, or to add power and fly away. It's no big deal in either case -- just depends upon your intent of the moment.

, and it is almost impossible to launch a large one by gusts alone (easy to lift it off the substrate very briefly, but that's not sustainable).
